Gear-box connection, wherein flanged joint, which refers to, is connected with each other including flange, gasket and bolt three as combined sealing structure
Releasable connection；That is, first flange disk 11 can be arranged in the first end of base 1, first flange disk 11 is used for and the
The gear-box flange of one gear-box is affixed；Second flange disk 12, second flange disk 12 can be set in the second end of base 1 simultaneously
For affixed with the gear-box flange of second gear case, and the gear-box flange of first flange disk 11 and first gear case can lead to
Cross that multiple bolt connection pieces are affixed, the gear-box flange of second flange disk 12 and second gear case can also connect by multiple bolts
Fitting is affixed.
Wherein, first axially opened up along motor is equipped on first flange disk 11 and second flange disk 12 to be threadedly coupled
Hole, correspondingly, also be provided on the gear-box flange of first gear case and the gear-box flange of second gear case respectively with the first method
First threaded connection hole of blue disk 11 and the first threaded connection hole of second flange disk 12 are in model corresponding in quantity
Two threaded connection holes, the setting of the first threaded connection hole and the second threaded connection hole be for being screwed in for bolt connection piece so that
Motor is closely connect with the cabinet of two sides gear-box.
Certainly, the set-up mode that motor can also have other different, such as can also be in the first spiral shell of first flange disk 11
Be respectively provided with steel-wire screw-socket in first threaded connection hole of line connecting hole and second flange disk 12, can make to connect in this way it is stronger,
So as to effectively prevent the dismounting of motor to wear；Further, it is also possible to be symmetrically arranged two on the both ends ring flange of base 1
A U-type groove 13, so, when motor and two sides gear-box assemble, by will be in two U-type grooves 13 and gear-box flange
Slot alignment, and cylindrical positioning pins are installed in hole, the pre-determined bit of motor and gear-box can be realized in this way.
Further, rotor shaft 2 includes the first shaft end 21 and the second shaft end 22, wherein the first shaft end 21 is for protruding into
In the axis hole of the shaft coupling of first gear case, pass through the company of the shaft of the affixed realization rotor shaft 2 and first gear case of the two
It connects；Second shaft end 22 is used to protrude into for the connecting pin of the shaft coupling of second gear case, to realize rotor shaft 2 and second gear
The connection of the shaft of case.
Specifically, the first shaft end 21 is equipped with the outer conical surface being axially arranged along rotor shaft 2, when the first shaft end 21 and the
When the shaft coupling of one gear-box is affixed, outer conical surface is used to fit closely with the shaft hole inner wall of the shaft coupling of first gear case, and
Outer conical surface is along rotor shaft 2 far from the axially tapered of the second shaft end 22, and in other words, the outer diameter of the first shaft end 21 is further away from
Two shaft ends 22 are just smaller, first axle end 21 can be inserted in this way in order to the axis hole of the shaft coupling of first gear case, to realize first
The shaft of gear-box is fastenedly connected with rotor shaft 2.
Second shaft end 22 is equipped with the inner circle taper hole opened up along the axial direction of rotor shaft 2, when the second shaft end 22 and second gear
When the shaft coupling of case is affixed, inner circle taper hole is used to fit closely with the connecting pin outer wall of the shaft coupling of second gear case, and inner circle
The inner wall of taper hole is along rotor shaft 2 close to the axially tapered of the first shaft end 21, and in other words, the internal diameter of inner circle taper hole is closer to
One shaft end 21 is just smaller, can enter the second shaft end 22 in this way convenient for the connecting pin of the shaft coupling of second gear case, to realize the
The shaft of two gears is fastenedly connected with rotor shaft 2.
So, above-mentioned connection type can be such that the rotor of motor and the shaft of two sides gear-box connect, so as to
Drive two sides gear-box to operate simultaneously, and constraint axially and radially provided to the rotor of motor, realize electromotor no axis hold,
Dual output operating.
Meanwhile first the outer conical surface of shaft end 21 be equipped with the ring shaped oil passage that radially opens up, ring shaped oil passage is for accommodating
Hydraulic oil, thus realize the effect of lubrication outer conical surface, meanwhile, hydraulic oil can also play the axis for making the shaft coupling of first gear case
The effect that hole swells, to be more advantageous to the assembly of the first shaft end 21 and the axis hole of the shaft coupling of first gear case.Correspondingly,
The end face of one shaft end 21 is equipped with oil filler point 211, and hydraulic oil can flow into the ring shaped oil passage of outer conical surface by oil filler point 211, this
Sample one, since the lubrication of hydraulic oil and reaming act on, the diaphragm coupling of gear-box can easily be pressed into the first shaft end 21.
It is of course also possible to using oil pump, hydraulic oil is filled by oil filler point 211, so as to so that the shaft coupling of first gear case axis
Hole distending, in order to assemble.
In addition, the center of rotor shaft 2 can be equipped with the through-hole 23 axially opened up along it, through-hole 23 is specially fabrication hole,
Through-hole 23 is used to pass through and screw in along the center of rotor shaft 2 for outside fuel injection mouth the center oil filler point of second gear case, passes through
The connection of the two can carry out hydraulic oiling.It is of course also possible to fill hydraulic oil to pump nozzle using oil pump, and pump nozzle is stretched
Enter through-hole 23 and connect with the center oil filler point of second gear case, so that 2 inner circle taper hole distending of rotor shaft, further facilitates dress
Match.
In order to optimize above-described embodiment, dual output asynchronous traction motor further includes several groups radiating subassembly 14, radiating subassembly
14 along base 1 lateral wall be uniformly distributed and be used for power supply machine heat dissipation.Preferably, the outer surface of base 1 can be set four
Group is uniformly distributed radiating subassembly 14, and any group of radiating subassembly 14 includes the radiating fin of multiple wavy distributions, every group of heat dissipation
Fin is parallel and symmetrical towards two sides by center, and the middle line of two radiating fins of arbitrary neighborhood is equidistant, radiating fin
There are certain casting angle, the outermost radiating fin of two groups of radiating subassemblies 14 of arbitrary neighborhood intersects for the side of piece and neutral surface
Setting.Certainly, the setting that the radiating subassembly 14 on base 1 can also have other different, as long as can satisfy setting for the heat dissipation of base 1
It sets mode within the scope of protection of this application, will no longer be unfolded one by one herein.
